These are very easy to start from seed and have really striking foliage. They've never bloomed for me.
2023 - From seed. I ended up with 5 or 6 and stuck them in the GH garden, mixed in with the bugleweed. The colors look nice together. Update - it got a little dry in that area for some reason, and they never got very big.
2021 - I had a bunch of these up from seed, but some varmint sneakily ate a lot of tiny starts while they were still under the humidity domes! None of these were spared.
2019 - I have quite a few and planted in a mass in the Z5. So far, they aren't really spreading like I'd hoped.
